It is all a matter of how useful it is already. If it is already much better than using the normal touch interface in many cases, the technology will evolve a lot in some way. There will be more users willing to pay for it, more competitors, and so forth. I really hope for this to happen. On the other hand, if it is not good enough to be an improvement over the normal touch interface it will likely not be very used if not to show it to your friends for the first months. Next phone you buy you'll not care if it has or not that feature (unless somebody else or newer iPhones will be able to improve it a lot), and the technology will hardly evolve. I don't still know as I don't have an iPhone 4s, and stories I read still can't tell me if it is going to be used a lot or not. Also in the specific case of Italian, I guess the at least the recognition can be near perfect as Italian is a lot simpler than English to turn into text (probably simpler than any other language given that things are spoken exactly as they are read). But then the interpretation I guess will pose very similar problems, with the disadvantage of not being a mainstream language.
